Handlingdevicesthataresensitivetoelectrostaticdischarge

Anycomputerpartcontainingtransistorsorintegratedcircuits(ICs)shouldbeconsideredsensitiveto electrostaticdischarge(ESD).ESDdamagecanoccurwhenthereisadifferenceinchargebetweenobjects. ProtectagainstESDdamagebyequalizingthechargesothatthemachine,thepart,theworkmat,andthe personhandlingthepartareallatthesamecharge.
Notes:
1.Useproduct-specicESDprocedureswhentheyexceedtherequirementsnotedhere.
Chapter1.Safetyinformation3
2.MakesurethattheESDprotectivedevicesyouusehavebeencertied(ISO9000)asfullyeffective.
WhenhandlingESD-sensitiveparts:
•Keepthepartsinprotectivepackagesuntiltheyareinsertedintotheproduct.
•Avoidcontactwithotherpeople.
•Wearagroundedwriststrapagainstyourskintoeliminatestaticonyourbody.
•Preventthepartfromtouchingyourclothing.Mostclothingisinsulativeandretainsachargeevenwhen youarewearingawriststrap.
•Useagroundedworkmattoprovideastatic-freeworksurface.Thematisespeciallyusefulwhen handlingESD-sensitivedevices.
•Selectagroundingsystem,suchasthoselistedbelow,toprovideprotectionthatmeetsthespecic servicerequirement.
Note:TheuseofagroundingsystemtoguardagainstESDdamageisdesirablebutnotnecessary.
–AttachtheESDgroundcliptoanyframeground,groundbraid,orgreen-wireground.
